GISCafe Special Report Questionnaire: Drones for GIS Mapping
September 6th, 2019 by Susan Smith
The FAA estimates that there will be nearly half a million registered commercial use drones in the U.S. by 2022 (FAA 2018 – 2038 Aerospace Forecast).
Drones, or UAVs or UAS, are being used in the GIS industry for such purposes as military surveillance, real estate, searching for hurricane activity, search and rescue missions, public health and safety, agriculture and in construction and countless other industries. In some cases, drones can provide greater resolution than satellite imagery. Their size and affordability makes them a valuable choice for scientists, power companies, surveyors, military actions and civilians and many others. They are also environmentally friendly and provide a low-cost option for gathering valuable data that can then be fed into a GIS.
Since drones can autonomously collect a vast range of data they are appealing to many use cases. Besides, they are light-weight and high performance. Satellite imagery has provided remote sensing data for mapping, but can often display low fidelity or limited visibility from cloud cover. High precision and accuracy can be achieved with aerial imagery, with planes equipped with high tech remote sensors. Photogrammetry, which makes use of overlapping photos to identify exact measurements between objects, is a useful way of gathering accurate models.
With GIS, the system is only as good as the information you give it. Drones or UAVs have the capability of assembling a vast amount of data, but it then needs to be collected in such a way as to be useful for the type of project it will be used for. There are numerous sensors and drones to choose from, plus software limitations and regulatory requirements.
What’s on board a drone? The UAV payload is responsible for gathering the data. Applications vary so the payloads can be inferred, action, or thermal cameras, high precision barometers or multispectral, LiDAR, or hyperspectral sensors.
The difference between drones and satellite imagery and aerial remote sensing imagery has to do with cost of equipment, trained personnel, environment and safety concerns and weather conditions.
Even a drone with high precision features on board is going to be a lot cheaper than aircraft sporting LiDAR and other instrumentation or a satellite launch and subsequent data collection. And it doesn’t take highly trained personnel to operate a drone. If there are troublesome weather conditions in the area, the loss of a drone is far less costly than the loss of an aircraft.
Below is a questionnaire on drones – please feel free to answer the questions that apply to your organization’s use of, development of, or interest in, drones or if you will, UAVs. Deadline for submissions is September 20th, 2019. Please include photos (no headshots or logos please), screenshots, videos appropriate to the subject matter. You can send your responses to me, Susan Smith, firstname.lastname@example.org
